Pollution is the introduction of contaminants into the natural environment that cause adverse effects. It discusses various types of pollution like air, water, soil, noise, and light pollution. The document outlines causes like industries, vehicles, and agriculture. Effects include health impacts and ecosystem damage. It provides measures to control different types of pollution such as treating wastes, using public transport, and limiting fertilizers. The most polluted world cities include Cairo, Delhi, and Beijing. The conclusion is that reducing pollution requires going green.

water pollution control and measurmentRekha Kumari
Today we all are facing the biggest problem that is scarcity of drinking water as the level of water is continually decreasing.
In many countries people die because of contaminated water as they do not have any water resources that contain pure water.
The first question comes in mind when we talk about water management is how can we manage water. For this we need some well-planned strategies like if we know the places where heavy rainfall occur, then we can put extra efforts there in order to save water for future use.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

(A Problem )
Muhammad Naveed Abbas
NC#3616
NUST (MCE)
2. I will be discussing….
Definition.
Types Of Pollution.
Causes.
Effects.
Measures.
Statistical data.
3. Definition
• Pollution is the introduction of
contaminants into the natural environment
that cause adverse change, in the form of
killing of life ,toxicity of environment ,
damage to ecosystem and aesthetics of
our surrounding .
(Wikipedia)
4. Definition (contd)
• An unwanted change in the environment
which involves the physical, biological and
chemical changes involving air, water and
land which affects the human life in one way
or the other”.
• Pollution has become a serious issue after
World War II in developing countries due to
unchecked rapid industrialization. Pollution is
the root cause of many diseases that kill and
disable living organisms.
12. Air Pollution
• Air pollution is contamination of
the indoor or outdoor environment
by any chemical, physical or
biological agent that modifies the
natural characteristics of the
atmosphere.
13. Sources Of Air Pollution
• Household combustion devices.
• Motor vehicles.
• Industrial facilities.
• Forest fires
18. How to control air
pollution?
• Maintaining a healthy distance between the
industrial and residential areas.
• The chimneys should be constructed tall in
size so that the emissions must be released
higher up in the environment
• The sulphur must be removed after burning.
• The gasoline must have anti knocking
agents..
• The mining area should be planted with trees.
19. How to control air pollution?
• The coal fuel should be replaced with gas
fuel to control the air pollution.
• The automobiles must be designed with
emission control system.
• The wastes must be removed and recycled
in the industrial plants and refineries.
• Plants like pine and ribes need to be
planted to metabolize the nitrogen oxides
and other pollutants.
20. How to control air
pollution?
• Timely servicing of the car helps to keep it
in a good condition, and also minimizes fuel
exhaustion
• Using public transportation helps to
prevent the air pollution
• Using alternative energy sources like solar
energy, hydroelectric energy, and wind
energy
23. Water Pollution…
• Water pollution is the contamination of
water bodies (e.g. lakes, rivers, oceans,
aquifers and groundwater).
• Water pollution occurs when pollutants are
discharged directly or indirectly into water
bodies without adequate treatment to
remove harmful compounds.
.
24. Water Pollution…
• Water pollution affects plants and
organisms living in these bodies of water.
In almost all cases the effect is damaging
not only to individual species and
populations, but also to the natural
biological communities
28. Water Pollutants…
• Detergents
• Chloroform
• Food processing waste, (fats and grease)
• Insecticides and herbicides.
• Petroleum hydrocarbons, (gasoline, diesel
fuel, jet fuels, and fuel oil).
• Lubricants (motor oil).
• From stormwater runoff.
29. Preventing Water
Pollution…
• Conserve water by turning off the tap.
• Mind what you throw down your sink or toilet.
• Don’t throw paints and oils in water channels.
• Use environment friendly household products,
such as washing powder, household cleaning
agents etc.
• Take great care not to overuse pesticides and
fertilizers.
• Don’t throw litter into rivers, lakes or oceans. Help
clean up any litter you see on beaches or in rivers
and lakes, make sure it is safe to collect the litter
and put it in a nearby dustbin.
30. Treating Polluted Water...
• Suspended, solid particles and inorganic
material can be removed by the use of
filters.
• Use of biological filters and processes can
naturally degrade the organic waste
material.
• After above two steps chemical additives
are supplied to get rid of any left-over
impurities.
34. Light Pollution
• Light pollution, also known as photo
pollution or luminous pollution, is
excessive, misdirected, or obtrusive
artificial light. Pollution is the adding-
of/added light itself, in analogy to added
sound, carbon dioxide, etc.
35. Light pollution Causes..
• Degradation of photic habitat by artificial
light.
• Alteration of natural light levels in the
outdoor environment.
• Due to Indoor light pollution human health
is compromised.
36. Controlling Light Pollution..
• Excessive lighting should be avoided.
• For Lighting an applicable design should
be followed.
• Light engineering should be applied for
streets.
39. Noise Pollution
• Noise pollution is displeasing or excessive
noise that may disrupt the activity or
balance of human or animal life.
• Noise means disgust or discomfort hearing
from environment.
41. Effects of Noise Pollution
• Noise pollution affects both health and behavior.
• Unwanted sound (noise) can damage
psychological health.
• Noise pollution can cause
• Annoyance
• Aggression .
• Hypertension .
• High stress levels .
• Hearing loss.
• sleep disturbances, and other harmful effects.
42. Effects of Noise Pollution
• Chronic exposure to noise may cause
noise-induced hearing loss.
• Older males exposed to significant
occupational noise demonstrate
significantly reduced hearing sensitivity
than their non-exposed peers.
45. Soil Pollution..
• Soil contamination or soil pollution is
caused by the presence of xenobiotic
(human-made) chemicals or other
alteration in the natural soil environment.
• It is typically caused by
• industrial activity.
• agricultural chemicals.
• improper disposal of waste.
46. Soil Contaminating
Chemicals…..
• Petroleum hydrocarbons.
• Polynuclear aromatic hydrocarbons.
Pesticides
• Lead and Other heavy metals.
48. How to control soil
pollution?
• Limit the use of fertilizers and pesticides
• Awareness about biological control methods
and their implementation
• The grazing must be controlled and forest
management should be done properly
• The afforestation and reforestation must take
place
• Proper preventive methods like shields should
be used in areas of wind erosion and wind
breaks
49. How to control soil
pollution?
• Treating Wastes of industries.
• Treating nuclear waste.
• Proper disposing of plastics and other
garbage materials.
50. Air Pollution do have….
• Health effects
• Effects on cardiovascular health
• Effects on breathing (asthma).
• Links to cancer
• Effects on children
• Health effects in relatively "clean" areas
